At 250, the transaction is processed based on the data regarding the information regarding the transaction and the at least one of the information regarding the physical location of the portable electronic device when obtaining the information regarding the transaction and the time of the day when obtaining the information regarding the transaction.

FIG. 6 illustrates a flowchart of one embodiment of a method 300 for processing a point-of-sale transaction such as the purchase of a plurality of products in a store in accordance with aspects of the present invention. At 310, a customer may receive information about a plurality of products for purchase in a store using a portable electronic device prior to placing them in their basket. For example, the obtaining of information about products for purchase may include the customer optically scanning decodable indicia associated with the products, e.g., using the camera located on the portable electronic device. The obtaining of information about products for purchase may also include the customer using the portable electronic device to interrogate an RFID (radio-frequency identification) tags associated with the products.

After completing shopping, at 320, the customer may activate the portable electronic device to receive information regarding the purchase of the plurality of products such as information regarding a financial account, e.g., credit card information or bank account information. The financial account information may be stored on the portable electronic device or may be accessible via the network. At 330, information regarding at least one of the physical location of the portable handheld device in the store and a time of the day is obtained when obtaining the information regarding the purchase of the plurality of products and/or accessing the financial account information.

At 340, a decodable indicia such as an optically scannable barcode is provided on a display of the portable handheld device. The decodable indicia is operable for paying for the products and operable for identifying at least one of the location of the portable handheld device and the time of the day when obtaining information regarding payment of the plurality of products.

At 350, the decodable indicia may be presented at a checkout for scanning (for example, portable electronic device 20 may be presented to point-of-sale transaction system 50 as shown in FIG. 7), and at 360, acceptance or denial of the point-of sale transaction may be made based on the decodable indicia. Alternatively, instead of the optical decodable indicia, the portable electronic device may transmit a wireless transmission such as a near field communication (NFC).

With reference to FIG. 8, a decodable indicia may be operable for identifying the current date and the time of the day when obtaining information regarding paying for the plurality of products, and operable for identifying the location of the portable electronic device when generating the decodable indicia. For example, a barcode 400 may include a first portion 440 of the barcode which identifies and may be used for authorizing payment for the products such as provide credit card or bank account information for paying for the products. A second portion 446 may identify the location of the portable electronic device when generating the decodable indicia for paying for the products. For example, the second portion may identify GPS coordinates. Third portion 448 may identify the current day and time when obtaining information regarding paying for the plurality of products. Alternatively, the barcode data may be one or more pointers to information stored, for example corresponding to data for authorizing payment for the products, corresponding to data for identifying the location of the portable electronic device when generating the decodable indicia for paying for the products, and/or corresponding to data for identifying the current day and time when obtaining information regarding paying for the plurality of products, in the point-of-sale terminal, store controller, or other server location.

As shown in FIG. 9, transaction system 50 such as a point-of-sale transaction system may include a processor 52, memory 54, and one or more input/output devices 56. An input/output device may include a point-of-sale terminals and cash registers having fixed or portable readers. Processor 52 may be operably configured to accept or deny the transaction based on the decodable indicia identifying the time of the day when generating the decodable indicia and a current time during checkout. For example, acceptance or denial may be based on determining whether the decodable indicia or wireless transmission identifying the time of the day when generating the decodable indicia matches the time of the day at checkout, is within a predetermined time range relative to a current time during checkout, and/or prior to a predetermined time. In addition to the decodable indicia or wireless transmission identifying a time of the day, the decodable indicia or transmission may also include the calendar day, e.g., month, date, and year. Acceptance or denial may be based on the decodable indicia or wireless transmission identifying the physical location of the portable electronic device when obtaining information regarding paying for the plurality of products or generating the decodable indicia and a location or within a predetermined location during checkout. Transaction system 50 may include a position location device such as a GPS chipset, etc. (or may be programmed with its current location or a range of locations) for identifying its location and real time clock for identifying the current time

From the present description, it will be appreciated that as more barcodes are being generated on mobile phones or read by Smartphones there is a concern for security and unintended proliferation of the barcodes since there is no printed medium that can be collected to take the barcodes out of circulation and prevent its reuse.

A data carrying medium, optical decodable indicia, wireless transmission, etc., may embed for example the following information:

-   -   1) GPS location coordinates;     -   2) Approved “tolerance” or distance radius within the defined         coordinates;     -   3) Date/Time or Time-only;     -   4) Approved “tolerance” band for days and/or time of day; and/or     -   5) Standard data content.

The data carrying medium may be in the form of a barcode, RFID tag, optical characters, near field communication, etc., and may reduce the likelihood of reuse of the data.

Suitable processing, software, logic or algorithms may be employed in a transaction systems such as a reader/host system to accept/reject a transaction regarding the encoded protocol, modify data routing or modify data format based on the relation of the date/time and location of the code and the date/time and location of the device when scanning the code. The transaction systems may include optical scanners that incorporate the optical scanning capabilities of U.S. Patent Application Publication No. US2009/0026267 by Wang et al., the entire contents of which are incorporated herein by reference.

Application software, also known as an application or an “app”, is computer software that may be downloadable to the portable electronic device such as a Smartphone and designed to allow the customer to scan the items to be purchased, obtain the current location and time, and generate and display or transmit the decodable data.

For example, in one embodiment of the process, a customer using a Smartphone for personal shopping may scan items in the store as they shop. The customer may observe the amount of the purchases as they are shopping, and when done and proceeding to the checkout, may cause the Smartphone to generate a barcode that is displayed on their screen to be scanned at checkout. This exemplary embodiment may allow for faster checkout processing times, e.g., avoid having a cashier scan each of the items at the checkout, while reducing the likelihood of fraud such as the customer adding extra items that were not scanned. The barcode may also provide identification of the customer which may be checked against a database of customers having authorization for such expedited checkout process.

Using the decodable data generated with location coordinates and a tolerance of about 100 feet (account for going to different checkout lanes) and a date/time stamp with tolerance of about 10 minutes (to account for wait time in checkout lane), the decodable barcode may not be able to be used or replicated for future use at a point-of-sale system such as an optical reader, upon scanning the code would compare its position to the location coordinates of the barcode and compare the current time to time in the barcode and only allow successful read if certain criteria is met. To further secure the barcode and prevent replication of the encoding standard, data could be encrypted so it is not obvious as to how the data content, location coordinates, and date/time are encoded. In addition, where the products contain RFID tags, the shopping cart of items to be purchased may be readily scanned without removing the items from the cart, and the total cost of the items compared to the payment amount generated by the portable electronic device and identified in the decodable indicia.

There are further applications that may be employed which incorporate aspects of the present invention in connection with embedding location coordinates and date/time stamp, and which scan, read, etc. the embedded location coordinates and date/time stamp in an optical decodable indicia, wireless transmission, etc. before processing a desired transaction.

The present invention may be implemented for issuing and accepting coupons. For example, a customer while shopping in a store may be able to receive decodable data regarding the purchase of an item, such as a coupon for an item, and wherein the decodable data may include the location, day, and/or time of day associated with obtaining the coupon as noted above. The coupon may be usable only at the store and within a limited amount of time.

The present invention may also be implemented in a guard tour patrol system for logging the rounds of employees in a variety of situations such as security guards patrolling property, technicians monitoring climate-controlled environments, and correctional officers checking prisoner living areas to ensure that the employee makes his or her appointed rounds.

For example, a portable electronic device may be operable to receive signals from an external positioning system and/or and external timing system, for example, as noted above. When an employee reaches certain points on their tour, the employee may obtain information at a checkpoint, such as optically scanning decodable indicia disposed on a placard associated with the checkpoint, interrogate an RFID tag disposed on a placard associated with the checkpoint, or receive a wireless transmission such as a near field communication (NFC) from a placard associated with the checkpoint, using the portable electronic device. The portable electronic device may log the information obtained at the checkpoint along with identifying information relating to at least one of the location of the portable electronic device, the day, and/or the time of the day when generating the log of the information obtained at the checkpoint.

Later, the information may be scanned or downloaded, e.g., as noted above, from the portable electronic device into a computer where the downloaded data may be compared to a database of predetermined data, e.g., serial number of the checkpoint, location of the checkpoint. Suitable programming may analyze the timing of the downloaded data regarding the time at each location.

Thus, while various embodiments of the present invention have been illustrated and described, it will be appreciated to those skilled in the art that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
